摘要
以广陵香粳为试验材料,研究播期、栽插密度、施氮量以及结实期水浆管理等主要栽培措施对产量及稻米品质的影响。结果表明:广陵香粳于5月10日左右播种,栽插密度为27.0～33.0万穴·hm^(-2),基本茎蘖苗为150.0万·hm^(-2),施氮量为240.0～255.0kg·hm^(-2),基蘖肥与穗粒肥比为7:3,灌浆结实期采用间歇灌溉法,低限土壤水势控制在-15kPa左右,不仅产量较高,而且稻米品质也较好。
Guanglingxiangjing is a high-yield and good-quality rice variety, especially with very good taste. In order to explore the production potential of this variety, optimal cultivation techniques including sowing time, cultivation density , N dosage and water management in flowering stage were investigated. The results suggested that it was easier to obtain high-yield and good-quality using following cultivation techniques for this variety: suitable sowing date was about May 10; optimal transpling density was 0. 27-0. 33 million hills and 1. 5 million tillers per hectare; total N applied was around 240-255 kg per hectare, with the ratio of base fertilizer to seeding fertilizer was 7 : 3; intermission irrigation during grain filling was required, and the lowest soil water potential was about -15 kPa.
